There's a Water Stain on My Ceiling and Nothing Is Above It (Port Townsend, WA)
A ceiling stain with no bathroom or roof directly over it is usually a supply line leak that has traveled along the framing. Here's how it gets found without opening the whole ceiling.

Port Townsend homeowners describe water stain on ceiling the same way: a wet historic basement, sometimes pressure that has faded for decades, and no idea where to look. We do. Sandy bluffs above the Strait, century-old lines with unknown routes and acreage toward Cape George tell us where to start, and thermal imaging camera tells us where to stop.
What usually causes water stain on ceiling in Port Townsend
In Port Townsend we check a drain or overflow leak before anything else, because pressure that has faded for decades is how it shows up here. Only when a fixture upstairs is used. Sandy bluffs above the Strait makes the signs misleading, so we confirm rather than assume.
Next: a supply line leaking in a wall or joist bay. Copper pinholed at a nail plate or a hanger, a cracked polybutylene fitting, a galvanized thread rusted through. With till toward Discovery Bay under small Victorian lots in Uptown, the symptoms can look identical to the first cause, which is why the meter test and the locate matter.
And condensation on a cold line or duct: shows in humid weather or near an uninsulated cold pipe. Less common on mid-century grid lots on Sheridan Street, but we've found it near Kah Tai Lagoon.
First steps on a Port Townsend property
In Port Townsend's Uptown and Downtown historic districts the service line may be a century old and its route unknown, so tracing comes first.
Do this before anyone digs clay seams in the uplands in Port Townsend: note whether the stain grows with rain, with fixture use, or constantly. Feel the stain: warm means a hot line. It takes minutes and it tells us whether the problem is on mid-century grid lots on Sheridan Street or inside the house.
How we fix it
The repair side is interior water leak detection. On waterfront near Point Hudson that means isolate hot and cold, then thermal and moisture in outwash sand under the historic districts where the problem actually is, then trace and listen. If what we expose is copper on the Hastings Avenue grid at the end of its life, we say so with the pipe in your hand.
